3 Claims.

Another object is to provide a novel combined chime and rolling hoopwhich will protect the top or bottom of the container, and which willnot be driven onto the container when the same is loaded, or subjectedto a great force.

Referringto the drawing, Fig. 1 is a vertical sectional view of thecontainer, and

Fig. 2 is a detailed sectional view of the combined chime and rollinghoop, and container closure.

I is a metal container composed of upper and lower annular metalsections 2 and 3 and having their adjacent edges welded together at 4.An annular metal band or rolling hoop 5 is welded to sections 2 and 3 atpoints along its edges as at 6 and l. The hoop 5 covers the welded joint4, reinforcing and concealing the same, giving a more sturdyconstruction to the container and at the same time is of the same heightas the end rolling hoops to provide a center rolling hoop or supportwhen the drum is horizontal. An annular metal band or rolling hoop 8extends beyond the outer end or top 9 of section 2 form- Rolling hoop 8is welded to the side of section 2 at points along the line at H andalong the line at the curved portion of section 2 at 12. The insidediameter of the chime I is less than the outside diameter of section 2of the container, thereby preventing the combined rolling hoop and chimefrom being driven onto the drum when the same is loaded or subjected toother force. Preferably the inside diameter of the chimes l0 and I1 issuch that functionally they are an extension of the side of thecontainer i. e., they lie in the line which would be formed by extendingthe container walls upward to the chime. Thus any pressure directly onthe chime is eiiectively transmitted and absorbed by the sides of thedrum and the tendency to dent the edges of the drum body itself isminimized.

The bottom of the container is cupped at l3, and is protected by anannular band or rolling hoop l4 which-is welded to the side of section 3vtainer.

at points along a line at l and to the curved portion of section 3 alonga line at l6, and extends beyond the end of section 3 forming a chime H.The inside diameter of chime. I1 is also less than the outside diameterof section 3 or the container.

A shallow inside well is formed in the top of the container by therecess at l8; the exterior raised portion of the well carries a closurel9 consisting of an internally threaded metal cap 2| which is threadedon threaded ring 22. A metal neck ring 23 having an annular flange 24fits snugly in threaded ring 22, and is welded to the edges of thecontainer opening. The lower edge of the neck ring is hammered orhammered and. welded into recesses or notches 25 in threaded ring 22 toprevent turning of the thread'ring. A cup shaped member 26 having anannular flange 21 is provided with a vent hole 28, and is secured to cap2|. A rubber gasket 29 forms a liquid tight seal between the flange 24and flange 21. The vent hole 28 in cup shaped member 26 and vent hole 3|in cap 2| permit the escape of any gases evolved from the contents ofthe container, yet permit the liquid in the container to leave the sameonly at a very slow rate. The cup shaped member inhibits the actual lossof liquid because it is designed to hold substantial quantities ofliquid and then to drain it back into the con- This is of greatimportance when shipping or transporting. liquids giving off gases orvapors, since the liquid in the container is almost continually inmotion and splashing against the venting device. This splashing is oftenvery violent and excessive amounts of liquid would be forced out andlost were it not for the cup shaped member. The recessed top of thecontainer and the closure permit the container to be completely drained.Openings 32 in chime l0 permit drainage of any liquid on top of thecontainer.

The container and closure or venting device may be formed of any metalsuitable to the material enclosed in the container. We have formed thesame .of aluminum and found it very satisfactory for such materials asdo not corrode aluminum and cause stoppage of the vent holes. and it isespecially suitable as a hydrogen peroxide container. As will be seenthis closure structure will permit the container and all parts of theclosure structure being fabricated of the same material, for examplealuminum, in all ,parts which come in contact with the liquid; at thesame time provision is made for such strength of closure thread as maybe needed, by constructing the threaded portion of metal substantiallyhardther permits the rolling hoops and chimes being made of metal whosegauge is substantially heavier than that of the main body of the drumwithout complicated interfolding of edges; or, the rolling hoo andchime, for purposes of rigidity and strength, may be constructed ofmetals other than the metal of the drum. Thus the drum body itself maybe made of substantially pure aluminum whereas the rolling hoop andchime may be constructed ofan aluminum alloy well adapted to stand theshock incident to transportation and use.

' It is obvious that many modifications may be made without'departingfrom the spirit and scope of the invention; and that more than twoannular sections may be welded together, and that the container may haveany number of rolling hoops. While welding of the rolling hoops to thebody section is shown as preferred in order to avoid slipping, the hoopscan be rolled to a tight fit, and if necessary slightly crimped into thedrum body, so that the welding may be dispensed with. Metal ring 23 maybe made integral with the top of the container as by rolling out themetal from the Opening in the body wall. If desired, any number of cupshaped members may be used, and may be secured directly to the metal capwith or without flanges or may be secured to the metal ring in any wellknown manner.

We claim as our invention:

1. In a cylindrical container an annular metal band at the end thereofforming an integrally constructed rolling hoop and chime, both of thesupporting edges of said rolling hoop being attached to said container.and the diameter of said chime being such that the chime lies in a lineformedby the extension of the walls of the container.

2. A rolling hoop for the end of cylindrical containers having a chimeintegrally constructed therewith, the diameter of said chime being suchthat the chime lies in a line formed by the extension of the Walls ofthe container, and the rolling hoop edges being attached to andsupported by the container walls at a plurality of points. I

3. A rolling hoop for the end of cylindrical containers having va chimeintegrally constructed therewith, the mean diameter of said chime beingequal to the mean diameter of the container adjacent to said chime andthe rolling hoop edges being attached to and supported by the containerwalls at a plurality of points.
